DATASHEET ISL8121 3V to 20V, Two-Phase Buck PWM Controller with Integrated 4A MOSFET Drivers FN6352 Rev 2.
00 October 27, 2009 The ISL8121 is a two-phase buck PWM controller featuring an input voltage range of 3V to 20V and integrated MOSFET drivers.
Precision voltage regulation is provided for point-of-load and other highcurrent applications that require efficient and compact implementation.
Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency allowing smaller filter inductors and reducing input and output ripple currents due to the ripple cancellation effect.
Lower ripple results in fewer input and output capacitors.
Smaller and low cost tra...
